    To make sure we don't have a translation error, could you give us your definition of hosted exchange. Thanks.
    1 1 was a racehorse.
    2 2 was 1 2.
    1 1 1 1 race 1 day,

      Ok,

      We are an ISP and want to issue a service (Hosted Exchange)

      It's like smaller company's can 'rent' a exchange server.

      So there are more different company's on only one exhcange server.
      But they cannot share info with eachother, the whole exchnage server is managed by us (me).

      I hope this is a little more accurate.

        Re: Hosted Exchange

        I have had a few people approach me about doing this, so I have most of the information to hand.

        How much cash have you got?
        It isn't cheap to do properly.

        It isn't just a matter of setting up Exchange and making a few changes to the server to isolate the users from each other. You need interfaces to allow your customers to manage their accounts, antivirus licenses, licensing from Microsoft, multiple servers, backup applications etc.
        Sign up with one of those who you would be competing with and see what you get for the money.

        Now I am looking at pricing in UK , but when I hit 50,000 most people run away. I usually predict somewhere in the region of 100,000 to get it going, including development costs.

        Then I tell them to look at what price One and One charge per mailbox per month (I think they start at 5 before tax here in the UK), means that you need a lot of customers to make it pay. Without paying overheads, you need about 1200 mailboxes a month before you can even look at repaying the costs. That is without profit, and paying for staff to run the servers for you.

        Don't forget there is the bandwidth bills - being an ISP you don't have that problem, but for anyone else the bills can clock up very quickly. Outlook isn't the most bandwidth efficient of applications.

        Oh and then there is the possibility of having to write off the entire investment in six months time when the new version of Exchange is released and your customers start demanding Exchange 2007 because as a hosted provider one of the selling points is the easy upgrade to the new version.

        Your best option at least to begin with is to look around to see if any of the major players are doing a white label version of their service. There are a couple here in the UK that do that.
        You can then label it with your own branding but someone else runs the infrastructure.

        When you start getting the numbers that makes things pay, then look at doing your own thing.

        Simon.

          Is it so hard to implement ? Damn...

          What about maintenance, also a hell of work?

          But do you have a tutorial of this, just to get a feeling of the complexity of the situation.

            Re: Hosted Exchange

            Exchange is designed for one company, where everyone can see everyone else in the GAL. It is also designed to be managed by an administrator using ADUC and ESM.

            Removing those three elements away from the management of Exchange, perhaps to a web based service takes some doing. It is possible to do, you either have to purchase something or get it written for yourself.

            If you were a corporation with 1500 or 2000 mailboxes then you would probably have at least one full time Exchange administrator, hosted Exchange is no different. If anything it is more complicated because you are having to use customised permissions.

            As for tutorials, you could look around for the kb articles on hosting virtual organisations, which give you an idea of the permission changes.

            The hosted Exchange crowd don't share their information. I have seen very little on it. Microsoft have a hosted Exchange solution, which is widely regarded as basic and most hosters write their own management interface.

            To give you an idea on where the numbers below came from... you are looking to purchase at least two backend Exchange servers, running Enterprise edition, two frontend servers running standard edition, lots of storage and probably another gateway machine to do the virus and spam scanning. I can easily spend 30 - 40k on the basics, before licensing the av, antispam, bes, SSL certificates, bandwidth, rack space etc.
